Acid/Base Neutralization
Scenario: A pH sensor is dipped in different solutions to measure their acidity or basicness. Note that lower pH corresponds to higher acidity of the solution and likewise that higher pH corresponds to basic solutions.Acid/Base Neutralization Multiple Choice Question:
Q: What will happen to the pH measurement when we dip the sensor node into the bleach, vinegar, and the milk?
INCREASE, DECREASE, DECREASE
Bleach is a basic solution which causes the first upward spike of the pH metric. When dipping the probe into the vinegar solution the pH falls because the vinegar is acidic. Also, the milk increases the pH because it is relatively more basic than the vinegar (and relatively close to being completely neutral if not for the lactic acid). Thus the pH measurement increases before decreasing and then increasing again.
